OIL-VALVE FOR GASOLENE-ENGINES.

SPECIFICATION formingpart of Letters Patent No. 635,218, dated October 17, 199.

Application filed June 7, 1899- Serial No. 719,714. (No model.)

To all whom it may concern:

Be it kn own that I, ALEXANDER WINToN, a citizen of the United States, residingat Oleveland,'in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Oil-Valves for Gasolene-Engines, of which the following is'a specification.

My invention relates to improvements in oil-valves for gasolene-engines, and pertains to a construction involving a pressure-regulated inlet-port valve carrying a yielding oil valve and an adjustable seat or nipplefor said oil-valve, all of which will be fully described hereinafter and particularly pointed out in the claims.

The accompanying drawing is a sectional View of my invention.

Referring now to the drawing, A indicates the end of the explosion-cylinder of a gasolene-engine which is provided with a projecting cylinder B. At the inner end of this cylinder B is provided a vaive-seatC for the explosive-inlet valve D. This cylinder Bis provided with an intermediate web E and at its outer end with an inwardly-projecting tubular head F with a closed inner end, and which serves to close the outer end of the cylinder B.

The inlet-port valve D is provided with a stem G, which passes through an inwardlyextending tube 131 of the centrally-disposed Web E and also through the web and has attached to it an outwardly-disposed cup-shaped piston I, which incloses the inwardly-extending cap F. This piston I fits neatly the inner bore of the cylinder 13, but does not fit closely the inwardly-disposed tubular portion F of the cap. This piston I is provided with an outwardly-projecting tube J, which passes through the tubular head F, and through which tube the stem G passes and also beyond the end of the tube. Situated between the cup-shaped piston I and the central web E is a spring K, which serves to hold the piston normally outward, and consequently to normally seat the inlet-port valve D. A pipe L is in communication at one end with the cylinder B at a point between the centrally-disposed web E and the piston I and at its outer end in communication with a pump actuated by the engine for supplying an air-pressure within the cylinder,in the manner fully shown and described in my Patent No. 582,108, dated May 4, 1897, and which need not therefore herein be more fully shown and. described. The piston I is clamped to the outer end of the valve-stem G by means of the nut M, and the extending end of the stem is provided with a longitudinal socket N, which receives an oilvalve stem P. Formed in this socket are registering longitudinal openings at, and passing through these openings and the said valvestem? is a pin Z), of a size to permit the valvestem to have a longitudinal movement within the said socket. Placed within the socket between the inner ends of this valve-stem and the inner end of the socket isaspring c, which normally holds the valve and its stem outward in respect to the said socket.

Q represents a tube which has one end in communication with the inner endof the cylinder B through the opening R, audits opposite end is in communication with the atmosphere. This tube Q may have interposed between its ends a carbureter but as that forms no part of my present invention it is not here shown or described.

S is an oil-reservoir supported in any suitable manner and with the lower end of which a pipe T communicates, and this pipe also communicates with a pipe U at right angles thereto, and passing through this pipe Uis a cut-off-valve stem V. At the inner end of this pipe T a nipple d is rotatably attached,

the opposite end of the nipple .being externally screw-threaded and passing through an internally-screw-threaded shoulder 6, formed upon the pipe Q. This nipple is provided at its inner end with an elongated valve-stem nopening f. The inner end of this opening is formed into a valve-seat g and receives the valve upon the outer end of the valve-stem P. From this description it will be noted that the inner end of the nipple furnishes a support and a guide for the outer end of the valve and valve-stem, as the opening sin the nipple is made sufficiently small to always insure the point of the needle-valve registering with its converging tapering wall when moved into a closed position.

It is desirable to provide at all times a tight fitting of the oil-valve when it is seated, and to accomplish this the nipple is longitudinally adjustable by screwing it through the enlargement 6 upon the tube Q and clampingit in its adjusted position by means of a clamping-nut i.

In adjusting the nipple, and thereby regulating the seating of the oil-valve, the nipple is turned until it is noted that the pin b,which unites the opposite end of the valve-stem P to the inlet-port valve-stem G, has a slight inward or backward movement, and then the nipple is tightened by the lock-nut t'. In this way any wear of the valve and the valve-seat is readily taken up, and it also enables me to provide a perfect seating of the valve, which will not necessitate the turning up of the cutoff valve V when the engine is not running. The nipple is provided intermediate its ends with a projection an, adapted to receive a wrench for adjusting it. By means of this adjustment the seating of the oil-valve and of the inlet-port valve can be made to occur at the same time and yet a tight fit of the oilvalve accomplished to prevent any leaking of the oil when the engine is not in operation.

The inwardly-extending tubular cap F and the outwardly-disposed cup-shaped piston I furnish a dash-potfcr preventing the hammering of the inlet-port valve and also of the oil-valve, which prevents not only injury and wear to the valves and the valve-seats, but also prevents a disagreeable noise which otherwise would occur.

I11 operation when the inlet-port valve D'is moved inward from its seat for admitting the explosive material the needle-valve is likewise removed from its seat, permitting a flow of liquid to the pipe Q, and this is conveyed through the said pipe to the explosive-inlet port through the opposite end R of the pipe Q. This arrangement insures a positive feed of the liquid to the pipe Q at each inward movement of the inlet-port valve, since the needle-valve is connected to the stem thereof, as before described. \Vhen it is desired to absolutely cut off the flow of the liquid, (as when the engine is out of operation,) the valve D is screwed to its seat, which will cut off the flow of liquid, as will be readily understood from the drawing.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
